K_EXTRAEINFO="This kernel is not supported by Gentoo If you have any issues, try
a matching vanilla-sources ebuild -- if the problem persists there, please file
a bug at http://bugme.osdl.org. If the problem only occurs with rt-sources then
please contact Ingo Molnar on the kernel mailinglist to get your issue resolved.
But first search the mailinglist-archiv if your problem is already 
discussed/solved: http://lkml.org/
